hi, new to this forum, wondered if anyone could answer a couple of questions on the egr valve on a 320 diesel 03 plate.
ok so all cleaned and back together except the small vacuum hose on the right side of the valve, its a short braided blaqck hose running from the valve but it now seems it doesn't go anywhere, at least I cant find any where to attach it to? its only 7inches but I cant find where to attach it to.
Question 1. does it need to be attached to anything and am I looking for something that does not exist? or could you explain where it goes?
Question 2. Should the egr valve open and close by pushing the valve manually off the car, or is the pressure needed it to operate more?
Im uncertain if it should as some people mention blocking it to prevent exhaust gasses recirculating into engine?
the car has been remapped and runs great. any advice appreciated
